class AliTPCInverseCorrection: public AliTPCCorrection


AliTPCInverseCorrection class

This is a wrapper that inverts an AliTPCCorrection. This is done by
swapping the CalculateCorrection and CalculateInverseCorrection functions.
The wrapped correction is supplied as a pointer and the class relies
on the fact, that this pointer keeps pointing to the right object.
However, the ownership is not changed, i.e. the wrapped correction
will not be deleted when this correction is destructed.

Function documentation

AliTPCInverseCorrection()
 default constructor
 (only meant for ROOT I/O)
AliTPCInverseCorrection(AliTPCCorrection* correction)
 Constructor that is creating the inverse of the supplied correction.
 It automatically sets the name ("inv_[correction name]") and tile
 ("Inverse of [correction title]").
~AliTPCInverseCorrection()
 virtual destructor
void Init()
 Initialization funtion (not used at the moment)
void Update(const TTimeStamp& timeStamp)
 Update function
void Print(Option_t* option = "") const
 Print function to check which correction classes are used
 option=="d" prints details regarding the setted magnitude
 option=="a" prints the C0 and C1 coefficents for calibration purposes
void GetCorrection(const Float_t* x, const Short_t roc, Float_t* dx)
 This is just calling the CalculateInverseCorrection of the wrapped
 correction -- or puts dr=0 if the latter is 0.
void GetDistortion(const Float_t* x, const Short_t roc, Float_t* dx)
 This is just calling the CalculateCorrection of the wrapped
 correction -- or puts dr=0 if the latter is 0.
